The present invention relates to a spraying apparatus, and moreparticularly to a moistening gun for a spraying device particularlyadapted for moistening fabric.

In the ironingof clothes and the pressing of fabrics it is necessary tohave the clothes or fabric slightly damp. Generally the necessary amountof dampness is applied to clothes which have been dried, by asprinkling, spraying or moistening device. Where clothes and fabrics areto be ironed or pressed shortly after the meistening or dampeningprocess, it is extremely mportant to have the moisture applied in anextremely finely divided form so that no appreciable drops of moistureproduce excessively wet areas. Particularly in the case of laundries,pressing establishments, and wherever large amounts of material are tobe handled, it would be desirable to provide a relatively simple tooperate and inexpensive to manufacture spraying device or moisteninggun.

In accordance with the present invention a relatively simple device isobtained having a minimum of movable parts and which neverthelessprojects a spray substantially in Vapor form` Numerous embodiments maybe added including a moistening device rigidly secured to an iron,goose, or the like.

It, therefore, is an object of the present invention to provide animproved relatively simple moistening gun.

It is still another object of the present invention to provide aconvenient to use light-weight spraying device for use in moisteningfabrics which are to be ironed or pressed.

Still another object of the present invention is to provide an improvedcombination of an iron or pressing means with a selectively operablemoistening device.

Other and further objects of the present invention subsequently willbecome apparent by reference to the following description taken inconnection with the accompanying drawings wherein:

' Figure 10 is a cross sectional View of a portion of the device shownin Figure 9. j

Referring more particularly to Figures 1 to 5 it will be seen that therehas been shown a pipe I2 which is connected to a suitabe source of uidunder pressure such as water, and which pipe iS provided with aT-connection I4 which in turn through suitable coupling means isconnected to a shut-off valve I6. The shut-olf valve I6 is connected toa ilexible conduit or tube I8 connected at an intermediate point to oneend of a spring 2S, the other-end of which is connected to a suitableoverhead support. The other end of the flexible conduit i8 is connectedto a moistening gun 22 having a body 24, a handle 26 and an operatingtriggerl or control member 28.

IThe handle 2S is secured to the body 24 by suitable fastening meanssuch as a screw 3B. At the forward side of the handle 2S there isprovided an adjustable stop member 32 which is arranged to act as alimit for the movement of the trigger member 28. lThe trigger memberadjacent its upper end bears against a shaft collar 3 mounted at anintermediate point on a reciprocable conduit 35 which is in fluidcommunication with the flexible conduit I8. The body 24 adjacent thetrigger 28 is provided with a suitable recess to accommodate the triggerand the collar 34. In addition a spring 38 is arranged between thecollar 311 and a portion of the body 24 so as to bias the reciprocableiiuid conduit Sii toward the forward portion of the body 24. At thefront end of the body 24, as may more readily be seen in Figures 3 and4, there is a forward body member 43 which threadedly engages the mainbody 24. Adjacent the forward end of the reciprocable tube 35 there isthreadedly mounted a whirling spray unit 42 which is shown inperspective in Figure 5. The spray unit G2 has a threaded portion d4 ofrelatively small diameter so as to engage the inner threaded surface ofthe end of the conduit 36. Adjacent the threaded portion there is acylindrical portion 45 having oppositely arranged attened areas 48 and58. Separated from the portion 4% by a recess 52 is a spray head 54 ofsimilar diameter. The spray head 54 is provided with two slots 5S and 58arranged at opposite sides so as to be at angles to each other. Thespray head 54 of the spray unit 42 has a recessed portion which carriesa resilient sealing member 60.

The body portion 4D is provided with a coaxial recess 62 having interiorthreads adjacent one end thereof as at 64. At the bottom of the recess62 there is positioned a biasing spring 36 which is arrangedto actagainst a packing member consisting of a resilient rubber-like annularring 68 mounted between two metal washers or rings 10 and 12. A nozzle14 having an axial discharge orifice I6 is threadedly mounted to engagethe threaded portion 64 of the body 40. The nozzle 'I4 has a coaxialbore 18 of a diameter substantially equal to the diameter of the sprayunit 42. The spray unit 42 is shown in Figure 4 in the position when thelever or trigger 28 of Figure 2 has been moved rearwardly against thestop 32 so as to withdraw the sealing member fill from the orifice 16.Fluid within the conduit 35 passes through a pair of openings llarranged just above the internally threaded end of the conduit 3S. Fluidpassing through the openings 80 then passes past the portion c of thespray unit 42 over the flattened areas 43 and 5f! thereof. The fluidthereupon circulates in the annular recess 52 and thence passes throughthe angularly related slits 56 and 58 so as to be discharged within thechamber 18 of the nozzle 74 in two relatively flat streams at angles toeach other. This action of the fluid under pressure in the nozzle 14causes the fluid to be projected through the orifice I6 in the form of awhirling relatively fine mist or fog. In order to cause the apparatus tospray it is only necessary to actuate the lever 2S which reciprocatesthe longitudinal conduit 36 a sufficient amount to withdraw the sealingmember a?! from the orifice 'i6 of the nozzle M. From the foregoing itwill be appreciated that the `mechanism provided is relatively simple tomanufacture, is light weight, and yet operates to produce improvedresults for the purpose intended. In spite of the fact that the numberof actuations of the trigger in the apparatus of this kind might beappreciably greater than in other spray gun apparatus, the relativelysimple structure is such vthat a minimum amount of maintenance and.repair will be required.

Another form of the present invention is disclosed in Figures 6, 7, and8 which merely has a body which serves both as a handle and a body. Thusthe arrangement in Figure 6 has many of the elements which correspondexactly to the elements in the foregoing figures, and hencecorresponding parts will be given similar reference characters. The body25 is modified slightly to accommodate the trigger 29 which is arrangedto have a member 3| pivoted thereon for engagement with the collar 34 onthe reciprocable conduit 36. The adjusting screw 32 is directly mountedupon the body 25. The remaining elements are in the same relation andidentical to corresponding parts shown in Figures 2 to el inclusive, Thedevice is grasped by the hand and pressure applied by a squeezingVaction to actuate the lever 29 thereupon to reciprocate the conduit 35sufficiently to open the discharge portion. in the nozzle 14.

`Another arrangement is illustrated lin Figure 9 which shows theinvention used in combination with a sad-iron or electric flat-iron 82having a handle 84. The handle 84 of the conventional structure has arcd extending therethrough which rod is usually secured to the uprightsupport members '86 and =88. In place of the rod mentioned, there isprovided a conduit which is connected to the flexible conduit I8. Theconduit 90 serves to retain the handle portion 84 between the uprightsupports 86 and 88 and extends forwardly to support on an extensionthereof the body 23 of a member otherwise generally corresponding to theapparatus shown in the previous embodiments. The principal difference inthe construction of the body 23 however is that the lower portion has afiuid conduit B which supplies liquid in back of the spray unit 42whereas in the previous constructions the liquid was Supplied through ahollow member or conduit 36 through port openings 8D. In the presentinstance the former conduit is replaced by a solid reciprocable rod 92which has its uppermost end supported in an adjustably positionedcap-like member 94. A suitable hand lever 96 is pivotally mounted in thebody 23 so as to be readily accessible by operation by one finger of thehand which is grasping the handle 84 of the flat iron or goose. From theposition shown in Figure 9 it will become apparent that it is possibleto project just ahead of the nose of the iron a spray so that forfinishing work for example just the adequate amount of moisture may beapplied to straighten out difficult wrinkles, and where a similararrangement is applied to a tailors goose adequate moisture may beselectively supplied for the pressing and shaping operations.

While for the purpose of illustrating and describing the presentinvention, certain preferred embodiments have been disclosed in thedrawing, it is to be understood that the invention is furthermoresusceptible of such variations as may be commensurate with the spiritand scope of the invention defined in the following claims.
